Yes, reading raw memory without structure is not useful as an exec-file (I see
now gdbserver protocol "qXfer:exec-file:read:" maps to the GDB command "file"
and not to the GDB command "exec-file") which serves mostly as a symbol file.
But for example vDSO is a memory readable ELF file. I remember some other
ROMs which also had structured format, parseable by BFD but not really
containing a filesystem. Amiga ROM contained a list of libraries, each one
with some PLTs etc.
